I was drawn to R like many others partly for the opportunity
to draw nice colorful graphs (occasionally ones with meaning too -)

We have a regression problem which could be solved elegantly if we could
figure out how to get the R residuals() function to accept missing
dependent variables.

I am using R 2.1.1 on a Fedora 3 Linux 32 bit PC.
If I compute the aggregated mean and the standard deviation I get
standard deviation values for factors where the mean was not computed.

Now im doing a statistical matching (datafusion) microsimulation
